Estimation of genetic parameters for production, composition and processability of milk from dairy sheep in a New Zealand flock

open access: yesNew Zealand Journal of Agricultural Research, Volume 68, Issue 5, Page 1107-1124, October 2025.
ABSTRACT This paper aimed to estimate the heritability and genetic correlations for processability (milk coagulation properties, cheese yield, and heat stability), milk production, and milk composition of dairy sheep in a New Zealand flock. Test‐day records from 169 ewes were obtained during the 2021–2022 season. Heritability estimates for yield traits

A validation study of loci associated with mastitis resistance in two French dairy sheep breeds

open access: yesGenetics Selection Evolution, 2019
Background The identification of loci associated with resistance to mastitis or of the causative mutations may be helpful in breeding programs for dairy sheep as it is for cattle worldwide.

Effects of the FecL major gene in the Lacaune meat sheep population [PDF]

open access: yesGenetics Selection Evolution, 2014
The major prolificacy gene FecL was first described in the Lacaune sheep meat breed Ovi-Test in 1998. A few studies estimated the effect of this gene on prolificacy but little data is available. In 2010, the Ovi-Test cooperative started genotyping FecL in all of their replacement ewe lambs.

Reference values for serum amyloid A, haptoglobin, lysozyme, zinc and iron in healthy lactating Lacaune sheep

open access: yesActa Veterinaria Scandinavica, 2018
Acute-phase proteins and trace elements are considered biomarkers of the immune response to infection, inflammation, trauma and other pathological conditions, as well as indicators of the health status and productivity of farm animals. Given the scarcity

Genomic selection strategies for the German Merino sheep breeding programme – A simulation study

open access: yesJournal of Animal Breeding and Genetics, Volume 142, Issue 3, Page 251-262, May 2025.
Abstract Genomic selection is widely implemented in livestock breeding programmes across species. Its potential is also evident for sheep breeding; however, it has several limitations, particularly because of the high genetic diversity across and within sheep breeds. In Germany, the predominant sheep breed is the Merino sheep. Until now, there has been

Factors affecting ewe's milk fat and protein content and relationships between milk yield and milk components

open access: yesCzech Journal of Animal Science, 2007
Test-day records of purebred Tsigai, Improved Valachian and Lacaune ewes were used to analyse the effect of environmental factors on milk fat and protein content.

Cut‐off value of somatic cell count and validation of differential somatic cell count by the fluoro‐optical method in subclinical mastitis milk in three sheep breeds

open access: yesInternational Journal of Dairy Technology, Volume 78, Issue 2, April–June 2025.
For the first time, the DSCC fluor optic method was validated for sheep milk. Optimal cut‐off values of SCC and DSCC were calculated for three dairy sheep breeds. Somatic cell count (SCC) is a test used for mastitis control in ewes, but there is no consensus on the cut‐off value.

Crossbreeding Performances and Variation Factors of Beni Guil Sheep in Morocco. I. Ewe Reproduction and Lamb Survival and Preweaning Growth Traits

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2008
An analysis of reproduction, survival and growth performances was performed on 484 Beni Guil ewes and their 461 progeny obtained by pure breeding or crossbreeding with D’man, Ile de France and Lacaune sires from data collected during 1994-98 at the ...

Symmetry-breaking phase-transitions in highly concentrated semen [PDF]

open access: yes, 2016
New experimental evidence of self-motion of a confined active suspension is presented. Depositing fresh semen sample in an annular shaped micro- fluidic chip leads to a spontaneous vortex state of the fluid at sufficiently large sperm concentration.

Markers for meat provenance and authenticity with an account of its defining factors and quality characteristics – a review

open access: yesJournal of the Science of Food and Agriculture, Volume 104, Issue 12, Page 7027-7084, September 2024.
Abstract Provenance is becoming increasingly important in meat supply chains as it lends products higher perceived quality. However, its precise definition and interpretation along with its associated characteristics factors have remained somewhat elusive.
